FAD ntawm AR raug txo rau FADH ₂ los ntawm kev hloov ntawm ob lub electrons los ntawm NADPH uas khi hauv NADP-binding domain ntawm AR. Cov qauv ntawm cov enzyme no tau txais txiaj ntsig zoo los tswj cov kev sib raug zoo ntawm cov khoom siv hluav taws xob NADPH thiab lees txais FAD rau kev hloov pauv hluav taws xob zoo.

Qhov enzyme txo FAD?

Nyob rau hauv no enzyme, FAD yog txo los ntawm succinate rau FADH₂ thiab ces yuav tsum tau reoxidized rau FAD kom txo ubiquinone rau ubiquinol (Daim duab 1 A). Los ntawm kev tsom xam ntawm cov qauv ntawm Complex II: FADH _{2: covalent system, peb xav tias proton abstraction los ntawm N1 atom yuav tsum koom nrog kev hloov mus rau Nws-A365.}

FAD pom qhov twg?

FAD yog ib qho redox cofactor kom ntseeg tau tias kev ua haujlwm ntawm ntau cov flavoenzymes feem ntau nyob hauv mitochondria tab sis tseem cuam tshuam rau kev ua haujlwm nuclear redox. Qhov kawg enzyme nyob rau hauv txoj kev metabolic uas ua rau FAD yog FAD synthase (EC 2.7. 7.2), cov protein uas paub tias yog nyob hauv ob qho tib si hauv cytosol thiab hauv mitochondria.

Thaum FAD yog oxidized lossis txo?

Zaj. Flavin adenine dinucleotide (FAD) yog ib qho tseem ceeb redox cofactor koom nrog ntau yam kev cuam tshuam hauv cov metabolism. Daim ntawv oxidized tag nrho, FAD, yog hloov mus rau daim ntawv txo , FADH _{2 los ntawm tau txais ob lub electrons thiab ob protons.}

Tus txheej txheem twg txo FAD?

Ib qho tseem ceeb hauv cellular respiration yog kev hloov ntawm lub zog mus rau molecule flavin adenine dinucleotide (FAD) los hloov nws mus rau FADH ₂Qhov no yog cov txheej txheem ntawm kev txo qis uas khaws lub zog hauv cov hluav taws xob siab hauv FADH_2.
